BAR-PILING MECHANISM FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 512,458, dated January9, 1894. Application filed August 13, 1892. Renewed November 18, 1893.Serial No. 491,355. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM A. SWEET, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Bar-Piling Mechanism for Rolling-Mills, of which thefollowing, taken in connection with the accompanying 1drawings, is afull, clear, and exact descripion.

My invention relates to mechanism for piling and straightening hotmetallic bars after they leave the finishing set of rolls in a train ofrolls in a rolling mill, by taking the bars from the trough or tablewhich received them from the rolls and placing them one upon anothersuccessively in a series of vertical chambers between the inner faces ofvertical standards, said standards being mounted upon suitable beds andadjusted sothat their inner faces are parallel and in straight alignmentwith each other, said chambers being adjusted so that their width is alittle more than that of the bars rolled; and in which ways, more orless inclined are detachably connected to said standards and table ortrough upon or over which the bars move or slide from said table ortrough down into said chambers.

My invention consists in the several novel features of construction andoperation hereinafter described and which are specifically set forth inthe claims hereunto annexed. It is constructed as follows referencebeing had -to the accompanying drawings, in which Figure 1, is a topplan of several benches of my invention, each bench consisting of acentral and two lateral standards. Fig. 2, is a rear elevation of threeof said benches. Fig. 3, is a sectional side elevation of one bench andthe mounting of one lateral standard. Fig. 4., is a top plan of onebench and the bed for another bench, and the slotways, therein, thestandards for that bench being removed, and also showing part of thereceiving trough, and one of the guide-ways in full lines leading to onepiling chamber from the trough, and showing by dotted lines a wayleading to the other piling chamber.

Timbers a-aare laid upon a foundation, and the bench beds b are securedthereto transversely. These beds are metallic and are provided withlongitudinal slots -cd enlarged at one end to permit the square head ofa bolt e to be inserted into each slot, and slide along in the slot,bringing the heads into the enlargement with the horizontal faces ofsaid slots. These slots may extend through the beds, or part way, beingthen T-shaped in cross section. Each bench consists of a centralvertical faced standard fmounted upon said bed by a bolt e through itsbase and engaging with a slot d near its left-hand end in Fig. 4; andlateral standards gh having. their inner faces vertical and parallelwith the faces of the standard f, these lateral standards beingrespectively secured upon said bed by bolts through their bases engagingwith the slots -cd. All of these standards are adjustable to vary thespaces between the lateral and the center standards by loosening thebolt of each and sliding the standard along on the bed.

By setting the central standards of all of the benches in alignment, Iadjust the lateral standards so that their vertical inner faces areequi-distant from and parallel to the vertical faces of the centralstandards, and this creates the piling chambers m between said verticalfaces. 7

Each bar, as it comes from the finishing rolls, passes into the trough p(or onto a table) of proper length.

Ways n each consisting of a bar or rod of iron are detachably connectedto the standards gand f by means of a; pin on the bar (seedotted linesin Fig. 3) [ittinginto a hole n' in the top of the standard, andextending through a loop 0' upon or under the trough pand these ways aremore or less inclined, so that when a rolled bar passes into the trough,it is lifted onto said ways and is conducted on slides down over theminto one of the chambers until it is full, when another chamber isfilled, said bars lying one upon another and becoming straightenedlaterally and longitudinally, until cool, when the pile is removed andthe bars cut to the length desired.

Any number of piling chambers may be created by varying the number ofvertical standards in each bench.

When one piling chamber is full, the ways beds, and arranged with theirvertical faces parallel, and bar-gniding ways adjustably connected tothe standards.

In witness whereof I have hereunto set my hand this 15th day of June,1892;

WM. A. SWEET.
